These lectures are meant to be self-contained, but
we necessarily omit numerous details,
while trying to make clear the basic ideas and results.
More complete accounts of cosmology and its
particle-physics aspects
may be found in various books [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Dark matter
candidates we consider in these lectures are
reviewed in Refs. [7]}, [8]}, [9]}, [10]}. Electroweak baryogenesis
is presented in detail in reviews [11]}, [12]}, [13]}; for reference,
a plausible alternative scenario, leptogenesis, is
discussed in reviews [14]}, [15]}.
Aspects of inflation and its alternatives are reviewed
in Refs. [16]}, [17]}, [18]}, [19]}, [20]}.
